To all whom it may concern Be it known that I, MARCELLUB R. BnN- Nm'r, acitizen of the United States, residing at WilkesBarre, in the county ofLuzcrne and. State of Pennsylvania, have invented new and usefulImprovements in Air-Valves for Internal-Combustion Engines, of which thefollowing is a specification.

This invention relates to improvements in air valves for internalcombustion engines and has particular application to a valve whereby airmay be admitted to the gas intake pipe of the engine in any desired quantity or volume. A

11 carrying out the present invention. it is my urpose to provide an airvalve which will manually controlled and whereby any desired volumeofair may be drawn into the gas intake pipe of the engine between themanifold and the carbureter and whereby any'preseure due to back firingwill be auto-- may relieved.

Tit/fa also my purpose to provide a valve of t/he class described whichwill be constructed in such manner that the air will be drawn into: thegas inlet pipe in the form of streams thereby breaking up the gaspassing through the supply pipe and into the manifold and ,Furthermore,I aim to provide a valve of the type set forth whereby the air drawninto the gas inlet pipe will be in the form of streams and maintain itsforce, incident to the stream formation, for a relatively long time.thereby efi'ectively commi'ngling with the gas passing through the pipeand breaking up the same with the result that an cilicient combustiblemixture is produced with a minimum consumption of liquid fuel.

With the above and other objects in view,

combination and art angemeut of parts here inafter set forth in andfalling within the scope of the claims.

In the accompanying drawings: Figure 1 is a view in side elevation of aninternal combustion engine equipped with an air controlling valveconstructed in accordance with the present in iention. Fig. 2 is atransverse sectional view through the gas intake pipe showing the valvestructure on an enlarged scale. Fig. 3 is a view in side elevation ofthe valve removed from the pipe. Fig. i is an enlarged verticalsectionalview therethrough. Fig. 5 is a transverse sectional view on theline 5-5 of Fig. 4.

Referring now to the drawingsin detail,

1 designates the 'carbureter or vaporizer of an internal combustionvengine, while 2 indi' cates the manifold connected with the cylindersand 3 the gas supply pipe connecting the carbiu'eter with the manifold.

Located in the supply pipe 3 and designed to admit air thereto is mylmproved air F2- ulating valve, such valve comprising, in presentinstance, a cylindrical sleeve 4 threaded into an opening in the supplypipe 3 at. a suitable distance above the carburetor. Arranged within thesleeve l longitudinally thereof is a seriesof tubes 5 opening into thesupply pipe 3 and having the outer ends thereof flush with the outeredge of the sleeve t. Threaded onto the outer end of the sleeve 4 is acollar 6 preferably of noncircular contour, while secured tothe collaris a plate 7 having an openin formed therein registering with the s eeve4. Projecting outwardly from the plate 7 above the connection betweenthe plate and sleeve is a. pivot pin 8 and pivotally moiuitcd upon suchpin is a closure in the form of a. plate 9 lying in face to far-econtact with the plate.7 and designed to close the outer ends of thetubes wi hin the sleeve 4. Projecting outwardly from the outer face ofthe'closure plate 9 and registering with he sleeve 4: is a cylindricalvalve casing 10 coaxial with the sleeve 4 and arranged within the valvecasing 10 is a valve disk 11 constructed of fiber or other suitablematerial and provided wi h a stem 12 extending into the casing it).Surrounding the stem 12 is a coiled expansion spring l3 having one endabuttingthe disk and the opposite extremity in engagement. with the endwall of the valve casing 10. such spring holding the valve disk infrictional engagement with th outer end of the sleeve 4-, such end ofthe s eeve constituting a sea; for the disk when the closure plate is inclosed position. The outer end of the pivot pin 8 is equipped with ahead 14. spaced apart from the outer face of the closure plate 9 andencircling the projecting end of the pin is a coiled expansion spring.15 abutting the confrontingportions of the head" 14 and the plate 10acting to hold theconfronting faces of the closure plate Land the plate7 in frictional engagement" and permitting movement of the closure plateabout the pivot pin to uncover the outer ends of the tubes 5 within ithesleeve 4 so edge of the closure plate so as to hold such plate normallyin closed position andreturn the same to such position upon the releaseof the arm 16.

From the foregoing description taken in connection with the accompanyingdrawings, the construction, mode of operation and manner of employing myinvention will be readily apparent.

Assuming the air regulating valve to be installed as illustrated inFigs. 1 and 2, the operator of the vehicle manipulates the respectivelever and so causes the arm 16 to swing the closure plate 9 about thepivot pin 8 and against the action of the restoring spring therebyuncovering the outer ends of the tube As the outer ends of the tubes areuncovered, the air rushes into the gas supply pipe 3, incident to thesuction created in such pipe in the operation of the engine. It will benoted that the air passing through the tubes 5 is projected into the gassupply pipe in the form of jets or streams thereby increasing the forceof the air and effectively breaking up the gas passi to the manifold andcommingling therewlth so that a highly combustible mixture is producedwith a m nimum consumption of gasolene. It will be. seen that any numberof tubes 5 may be brought into service independently of, the remainintubes thereby permitting the volume of air passing through theregulating valve to be regulated in accordance with the speed of theengine.

When the closure plate is in closed position, the valve disk 11 seatsupon the outer end of the sleeve 4 and is held against such seat bymeans of the spring 13 thereby effectively closing the outer ends of thetubes 5.

Should the engine back fire, the pressure thus setup will cause thevalve disk 11 to disengage the seat against the action of the spring 13thereby relieving such pressure.

lVhile I have herein shown and described one preferred. form of myinvention by way of illustration, I wish ,it to be understood that I donot limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claims without departing from the spirit ofthe invention. For instance, a. metallic plug having a series oflongitudinal passages therein may-be substituted for the plurality oftubes within the sleeve, or any other structure may be utilized, inplace of the tubes within the sleeve, which is capable of delivering airto the intake pipe or manifold in individual jets or streams.
